摘要
以微介孔ZSM-5分子筛为载体,采用等体积浸渍法制备了新型有序微介孔非均相Fe-Ce/ZSM-5Fenton催化剂。采用红外光谱和氮气吸附-脱附对催化剂进行表征,通过H_2O_2协同降解甲基橙模拟废水,考察了进水p H、甲基橙浓度、催化剂加入量、H_2O_2浓度及反应温度对催化剂性能的影响。结果表明:制备的Fe-Ce/ZSM-5保持了ZSM-5的骨架结构,且具有较大的比表面积;在进水pH为5.0、甲基橙浓度100 mg/L、催化剂加入量1.0 g/L、H_2O_2浓度20 mmol/L及反应温度20℃的条件下,甲基橙脱除率为87%,铁离子流失量仅为0.019mg/L。
A new type ordered microporous Fenton-like Fe-Ce/ZSM-5 catalyst was prepared by pore- volume impregnation method and characterized by FT-IR and Ne adsorption/desorption method. Themethyl orange as a simulative waste water and H2O2 as an oxidant were used to investigate the effect of operation factors on performance of the Fenton catalyst for methyl orange removal. The factors tested include feed pH,methyl orange concentration, dosage of the Fenton catalyst, H202 concentration, and reaction temperature. The characterizations indicate that Fe-Ce/ZSM-5 catalyst retains the framework of ZSM-5 and possesses a relative larger surface area. The results show that the methyl orange removal is 87% and the iron ion loss is only 0. 019 mg/L under the conditions of feed pH of 5.0,methyl orange concentration of 100 mg/L, catalyst dosage of 1.0 g/L, H2O2 concentration of 20 mmol/L, and reaction temperature of 20 ℃.
